304 No.4 finish - deysteel

304 No.4 finish 304 304L 304H belongs to austenitic stainless steel, it is the most widely used in the 300 series materials. On the whole, the 304 304L 304H has very similar characteristics, the only difference lies in the level of carbon content, so there will be a little difference more or less in the application filed, but the overall application is the same.

No 4: The Workhorse Finish - Australian Stainless Steel

By using grade 316 with a No 4 finish in aggressive environments, the corrosion resistance is negated and may be less than on 304 with a 2B or BA finish. Figure 3: The acceleration of the corrosion of the surface at Ra above 0.5 micrometres is apparent.

SSINA: Stainless Steel: Finishes

Surface chromium has been lost during the previous processing steps, and, without removal of the scale, the stainless steel would not provide the expected level of corrosion resistance. Chemical removal of this scale is called pickling or descaling, and it is the final processing step.

304 stainless steel sheet #4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes. The 304 stainless steel sheet #4 finish has a PVC film on one side to help protect against scratching during fabrication and installation.

No. 4 Polished Finish | Penn Stainless Products

No. 4 Polished Finish. No. 4 Finish is produced with short, parallel polishing lines. These lines extend uniformly along the length of the coil. It is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives. Depending on requirements, the final finish can be between 120 to 320 grit.

304 vs 316 Stainless Steel | Metal Casting Blog

316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel, and contains a similar material make-up. The key difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum.
